Here my json response,
"stops": [
{
"location": "The Sachdevs, 17, GAA 4th Ln, Thousand Lights West, Nungambakkam, Chennai, Tamil Na
"latlong": {
"lon": 80.250285901129,
"lat": 13.05583158449
},
"stop_code": "stop_1522754972",
"status": ""
},
]
error in this line :
jSONObject cat_object2 = latLong_object.getJSONObject(j); Object
cannot appolien in int
Here my java code,
Any one give me the solution.
Object stops = response_object.get("stops");
if (stops instanceof JSONArray) {
JSONArray stops_array = response_object.getJSONArray("stops");
if (stops_array.length() > 0) {
maplist.clear();
for (int k = 0; k < stops_array.length(); k++) {
JSONObject cat_object = stops_array.getJSONObject(k);
MultipleLatLongPojo pojo = new MultipleLatLongPojo();
pojo.setLocation(cat_object.getString("location"));
pojo.setStopcode(cat_object.getString("stop_code"));
pojo.setStatus(cat_object.getString("status"));
JSONObject latLong_object = cat_object.getJSONObject("latlong");
if (latLong_object.length() > 0) {
for (int j = 0; j < latLong_object.length(); j++) {
JSONObject cat_object2 = latLong_object.getJSONObject(j);
MultipleLatLongPojo pojo2 = new MultipleLatLongPojo();
pojo2.setMulti_lat(cat_object2.getString("lon"));
pojo2.setMulti_lon(cat_object2.getString("lat"));
}
} else {
}
}
}
}
Your latlong property in the json is not an array but an object with two properies (lat and lon), so you do not need to iterate through it's length and this part of your code:
JSONObject latLong_object = cat_object.getJSONObject("latlong");
if (latLong_object.length() > 0) {
for (int j = 0; j < latLong_object.length(); j++) {
JSONObject cat_object2 = latLong_object.getJSONObject(j);
MultipleLatLongPojo pojo2 = new MultipleLatLongPojo();
pojo2.setMulti_lat(cat_object2.getString("lon"));
pojo2.setMulti_lon(cat_object2.getString("lat"));
}
}
should be something like this:
JSONObject latLong_object = cat_object.getJSONObject("latlong");
if(latLong_object != null) {
MultipleLatLongPojo pojo2 = new MultipleLatLongPojo();
pojo2.setMulti_lat(latLong_object.getString("lon"));
pojo2.setMulti_lon(latLong_object.getString("lat"));
}

Hello My simple Json is and i have error org.json.JSONException: Index 2 out of range can you help me to solve this problem ? :
[
{
"cat_id": 593,
"title": "آلرژی و ایمونولوژی",
"sub_cat": [
{
"cat_id": 594,
"cat_title": "متخصص",
"cat_parent_fk": 593
},
{
"cat_id": 595,
"cat_title": "فوق تخصص",
"cat_parent_fk": 593
}
]
and get this json with this code but i have some error and just show two item of my json >15 item :
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
for (int i = 0; i < response.length(); i++) {
try {
Cats cats = new Cats();
JSONObject jsonObject = (JSONObject) response.get(i);
String cat_id = jsonObject.getString("cat_id");
String title = jsonObject.getString("title");
String image_add = jsonObject.getString("image_add");
String image = jsonObject.getString("image");
JSONArray jsonArray = jsonObject.getJSONArray("sub_cat");
for (int j = 0; j < jsonArray.length(); j++) {
JSONObject object = jsonArray.getJSONObject(i);
int sub_cat_id = object.getInt("cat_id");
String sub_cat_title = object.getString("cat_title");
int sub_parent_fk = object.getInt("cat_parent_fk");
Log.i("log", "onResponse: "+ sub_cat_id + sub_cat_title + sub_parent_fk);
}
cats.setCat_id(cat_id);
cats.setTitle(title);
cats.setImage(image);
cats.setImage_add(image_add);
list.add(cats);
catsAdapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
Instead of i you should use j here as
JSONObject object = jsonArray.getJSONObject(j);
// ^^
Let's assume that your response has 3 json objects and every sub_cat has 2 objects so during the parsing of 3rd object of response (when i is 2) but sublist has 2 objects (index 0,1) so know (as mentioned above) this will try to fetch 3rd object from an array(sub_cat) of 2 objects, hence the issue so use
for (int j = 0; j < jsonArray.length(); j++) {
JSONObject object = jsonArray.getJSONObject(j);
// j represents the size of sub_cat. ^^
...
}
I have the following JSON struncture:
{
"schedule":{
"day":[
{
"id":"Monday",
"items":[
{
},
{
}
]
},
{
"id":"Tuesday",
"items":[
{
},
{
}
]
}
]
}
}
And what I basically want to do is reach the items array inside the day array which is inside the schedule object.
But whenever I try to get the second JSON array, I get getJSONArray
(int) in JSONArray cannot be applied to (java.lang.String).
JSONObject baseJsonResponse = new JSONObject(dayJSON);
JSONArray dayArray = baseJsonResponse.getJSONObject("schedule").getJSONArray("day").getJSONArray("items");
You should use Two for loop respect to JSONArray.
JSONObject obj = new JSONObject(success);
JSONObject JOBJ_Schedule = obj.getJSONObject("schedule");
JSONArray schedule_Array = JOBJ_Schedule.getJSONArray("day");
for (int i = 0; i < schedule_Array.length(); i++)
{
JSONObject jOBJ = schedule_Array.getJSONObject(i);
JSONArray jArray = jOBJ.getJSONArray("items");
for (int j = 0; j < jArray.length(); j++)
{
JSONObject jOBJNEW = jArray.getJSONObject(j);
}
}
Looks like day is a list of objects. So basically, you'd have to do something like getJSONArray("day").get(0).getJSONArray("items").
you can try this
try {
JSONObject baseJsonResponse = new JSONObject("dayJSON");
JSONObject schedule= baseJsonResponse.getJSONObject("schedule");
JSONArray day=schedule.optJSONArray("day");
for (int i=0; i<day.length(); i++) {
JSONObject data = day.getJSONObject(i);
String id = data.getString("id");
JSONArray items = data.getJSONArray("items");
for (int j = 0; j < items.length(); j++) {
JSONObject data2 = day.getJSONObject(i);
String str = data2.getString("YOurkey");
Log.e("categories", str);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
According to the JSON you provided, baseJsonResponse.getJSONObject("schedule").getJSONArray("day") will return you a JSONArray instead of JSONObject.
There is a "item" JSONArray inside each "day" JSONObject. < May be this is the reason.
You can try
for(int i = 0 ; i < baseJsonResponse.getJSONObject("schedule").getJSONArray("day").length() ; i++){
JSONArray itemArray = baseJsonResponse.getJSONObject("schedule").getJSONArray("day")
.getJSONObject(i).getJSONArray("items");
}
Please help me to parse the following JSON data given below:
{

user_id: "1",
name: "Dave Greeneberg",
email: "daveneberg#example.com",
profile_photo: "http://phontest.lbch.com//users/user1.jpg",
contest_count: "3",
photo_count: 19,
win_count: "0",

]
}

}
I tried the following code but values in arrayList_ph is null. I am confused about how to parse this JSON content.
JSONObject object = new JSONObject(json);
JSONArray arr = object.getJSONArray("posts");
for (int index = 0; index < arr.length(); index++) {
JSONObject object1 = arr.getJSONObject(index);
user = arr.getJSONObject(0).getString("name");
user_email = arr.getJSONObject(0).getString("email");
user_profile = arr.getJSONObject(0).getString("profile_photo");
user_count = arr.getJSONObject(0).getString("count");
user_photo_count = arr.getJSONObject(0).getInt("photo_count");
contest_count = arr.getJSONObject(0).getString("contest_count");
win_count = arr.getJSONObject(0).getString("win_count");
JSONArray ph_arr= arr.getJSONObject(0).getJSONArray("photos");
for (int in = 0; in < ph_arr.length(); in++) {
arrayList_ph.add(ph_arr.getString(in));
}
}
Please help me to parse that field.
Please try this solution.
This solutions is worked for me.
JSONObject object = new JSONObject("");
JSONArray arr = object.optJSONArray("posts");
for (int index = 0; index < arr.length(); index++) {
JSONObject object1 = arr.optJSONObject(index);
user = object1.optString("name");
user_email = object1.optString("email");
user_profile = object1.optString("profile_photo");
user_count = object1.optString("count");
user_photo_count = object1.optInt("photo_count");
contest_count = object1.optString("contest_count");
win_count = object1.optString("win_count");
JSONArray ph_arr = object1.optJSONArray("photos");
for (int in = 0; in < ph_arr.length(); in++) {
String str = ph_arr.opt(in).toString();
arrayList_ph.add(str);
}
}
change your parsing code to this ,
JSONObject object = new JSONObject(json);
JSONArray arr = object.getJSONArray("posts");
for (int index = 0; index < arr.length(); index++) {
JSONObject object1 = arr.getJSONObject(index);
user = object1.getString("name");
user_email = object1.getString("email");
user_profile = object1.getString("profile_photo");
user_count = object1.getString("count");
user_photo_count = object1.getInt("photo_count");
contest_count = object1.getString("contest_count");
win_count = object1.getString("win_count");
JSONArray ph_arr= object1.getJSONArray("photos");
for (int in = 0; in < ph_arr.length(); in++) {
String str = ph_arr.get(in).toString();
arrayList_ph.add(str);
}
}
Try -
JSONObject object = new JSONObject(json);
JSONArray arr = object.getJSONArray("posts”);
for (int index = 0; index < arr.length(); index++) {
JSONObject object1 = arr.getJSONObject(index);
user = object1.getString("name");
user_email = object1.getString("email");
user_profile = object1.getString("profile_photo");
user_count = object1.getInt("count");
user_photo_count = object1.getInt("photo_count");
contest_count = object1.getString("contest_count");
win_count = object1.getString("win_count");
JSONArray photos_arr= object1.getJSONArray("photos");
for (int in = 0; in < ph_arr.length(); in++) {
String str = ph_arr.get(in).toString();
arrayList_ph.add(str);
}
}
Please cross check Following:
1) I think your json response is not properly formatted.
Validate from this: https://jsonformatter.curiousconcept.com/
Your json response should be :
{
"posts":[
{
"count":1,
"user_id":"1",
"name":"Dave Greeneberg",
"email":"daveneberg#example.com",
"profile_photo":"http://phontest.lbch.com//users/user1.jpg",
"contest_count":"3",
"photo_count":19,
"win_count":"0",
"photos":[
{
"image":"images/contest/diwali1.jpg"
},
{
"image":"images/contest/diwalc2.jpg"
},
{
"image":"images/contest/145043cd811.png"
},
{
"image":"images/contest/145043def03411.jpg"
},
{
"image":"images/contest/14504ger11.jpg"
}
]
}
]
}
2) If that still does not work...Try debugging and post your log please...
I have this data form this URL
http://api.clicky.com/api/stats/4?site_id=32020&sitekey=71bf7c1681e22468&type=visitors&output=json&json_callback=data%22
and how to get this in android,
my problem is how to access all this objects and array, help me
[
{
"type": "visitors",
"dates": [
{
"date": "2014-12-25",
"items": [
{ "value":"70" }
]
}
]
}
]
JSONArray jsonArray = new JSONArray("here is your json string ") ;
int count = jsonArray.length() ;
for (int i = 0; i < count; i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i) ;
String type = jsonObject.optString("type") ;
JSONArray datesArray = jsonObject.optJSONArray("dates") ;
int datesCount = datesArray.length() ;
for(int j = 0; j< datesCount; j++){
JSONObject dateItem = datesArray.get(j) ;
String dateStr = dateItem.optString("date");
JSONArray itemsArray = dateItem.optJSONArray("items");
for(int f = 0 ; f < itemsArray.length(); f++){
JSONObject valueJson = itemsArray.get(f);
String value = valueJson.optString("value");
}
}
}
I think, you can use GSON library for parsing your JSON. Just create class for JSON and use this code:
new Gson().fromJson(json, MyGsonClass.class);
I cannot figure out why my parsing is not working, this is my JSON:
{
"fileVersion":"1.0",
"graves":[
{
"ID_grave":"1",
"ID_line":"1",
"sequence":"1",
"persons":[
{
"ID_person":"1",
"name":"Janez",
"surname":"Novak",
"dateBirth":"1956-08-11",
"dateDeath":"2014-02-12",
"important":"0",
"imp_desc":""
}
]
},
{
"ID_grave":"2",
"ID_line":"1",
"sequence":"2",
"persons":[
{
"ID_person":"2",
"name":"Mojca",
"surname":"Novak",
"dateBirth":"1953-02-13",
"dateDeath":"2012-04-08",
"important":"0",
"imp_desc":""
}
]
}
]
}
This code is working, when I want to get the first JSONObject:
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
lineArrayList.add(grave.getString("ID_line"));
graveArrayList.add(grave.getString("ID_grave"));
}
But I would like to get the "persons" array in "graves" object. This should work but it's not, I am getting only the first persons array, where the name is Janez and not the second array where the name is Mojca:
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.getJSONArray("persons");
for (int k = 0; k < persons.length(); k++) {
//The problem was because of the index i, you have to change to k and it will work
JSONObject grave = persons.getJSONObject(i);
nameArrayList.add(grave.getString("name"));
surnameArrayList.add(grave.getString("surname"));
}
}
graves is a JSONArray and persons is a JSONArray into graves
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.optJSONArray("persons");
if (persons != null) {
for (int j = 0; j < persons.length(); j++) {
}
}
}
Do your parsing as follows ,
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.getJSONArray("persons");
for (int k = 0; k < persons.length(); k++) {
JSONObject grave = persons.getJSONObject(i);
nameArrayList.add(grave.getString("name"));
surnameArrayList.add(grave.getString("surname"));
}
}
Try This:
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.optJSONArray("persons");
if (persons != null) {
for (int j = 0; j < persons.length(); j++) {
JSONObject grave= persons.getJSONObject(i);
lineArrayList.add(grave.getString("ID_line"));
//so on..
}
}
Ok only today I discovered that I am getting the data only from the first persons array and from the second where for example is a person with a name Mojca..I tried all the three given solutions but nothing works..
